GRAIN-THRASHER AND CLOVER-SEED HULLER.

SPECIFICATION forming part of Letters Patent No. 259,157, dated June 6, 1882. ApplicationA med Maren 21, :reeel (No model.)

To all whom it may concern:

Be it known that I, GHARLEs H. HoRToN, of Wellington, in the county ot' Lorain and State of Ohio, have invented a new and Improved Combined Grain-Thrasher and Clover- Seed Huller, of which the following is a full, clear, and exact description.

This invention consists of improvements in grain-thrashing and clover-seed-hulling machines, the said improvements being designed to simplify the contrivance,whereby the thrashing and'hullingl apparatus may be embodied in one machine, so as to be worked with greater facility than as heretofore arranged, all as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicate corresponding parts in all the figures.

Figure l is' a longitudinal sectional elevation of my improved machine. Figs. 2 and 3 are horizontal sections of parts of the same on lines w and y y, respectively, of Fig. l; and Fig. 4 is a longitudinal sectional elevation through the huller.

A represents the thrashing-cylinder, working in the perforated concave B, the grain or clover to be thrashed being supplied to it from the feeding-table C in the usual manner. From the cylinder the thrashed grain is discharged over the perforated apron D onto the lower end of the separator E, the construction of which is one of the improvements of my invention, the same being a series of, say, four long strips, a, Fig. 3, of wood or other material, arranged side by side between the sides F of the separator-case, with the edges separated a little to allow some ofthe grains to fall through, also having perforations for that purpose, and being pitched on a slight ascending inclination from the cylinder A, and mounted near the lower end on the multiple-crank shaft G, and on the vibrating supporting-arms Hat the other end, the several cranks of the shaft being pitched reversely to each other successively for each successive section a, so that as one works forward those next to it work back- Ward; and upon each section there are several saw-tooth-shaped straw-breakers, I, mainly in the form of thin triangular plates with one end notched and set uppermost and with the base end toward the upper end of the separator, the arrangement being designed so that when the separator-sections descend by the crank movement these notched straw-breakers I will draw back under the straw, and so engage it that by the forward movement they will not only advance the straw along up the separator, but will break and separate it and the uutliraslled heads or portions thereof in a manner to eiciently supplement the cylinder as a thrashing device also.

The crank G is tobe driven by any approved means of connection with the operating mech- Yanism for working the separator. (Not shown From this separator the straw goes to the stacker, as usual, and the grain falls upon the vibrating bottom J, suspended on the extensions KofarmsH,andtherockerlinksLbeingworked by the former. From along the upper portion of this bottom J the grain is carried down-onto the perforated portion M of said bottom J, through which it falls to the shaker N, which delivers it at O to the fan-blower P, by which it is blown over apron Q into the grain-spout R, to be delivered from the machine, the chaffl and otherlight matters being blown away from over the cleaner S. vThe grains that may be blown over bottom T, together with heads, &c., are caught by the guard U and spout Vaud discharged thereby into the elevators W, to be returned to the cylinders, it' desired, or to the fan, as the conditions may require. In the latter case the elevator is opened by a slide (not shown) in its bottom over the conveyer X, which receives the said matters therefrom and discharges them upon the bottom J. The shaker N, receiving the grain, chad, &c.,from the shaking bottom J, conducts the matters falling upon it along in the direction of the air-blast created by the fan, and delivers them upon the cleaner S by a slight descent in front of the fan, where the said blast has powerful effect in carrying oft' the light matters. This shaker is suspended by the links Z, pivoted to the case-sides F, and it is operated by one or more connecting-rods, b, from the crankshaft Gr. Whatever grains fall directly from the cylinderA through the perforations of the concave B are received upon the forward portion of the shaker N and are passed along with the rest to the fan.

IOO

For the purposesof the clover-huller attachment, the cylinder d of which is located under shaker N in advance of the fan, this shaker N has an opening covered by removable sections c, directly over the said cylinder d, for the huller-cylinder d to rise up through, as shown in Fig. 4, when adjusted for Work, and through which the unhulled seed fall to the cylinderconcave f at g, and are delivered therefrom at l1., Fig. 4. The huller-cylinder concave f is pivoted by arms i to the frame at j, and is oonnected by arms 7c at the side opposite to said pivots to the elbow-lever l, arranged on roekshaft on, so that it is swung up into position by depressing` the handle n of said rock-lever l, and is secured in the Working position by a binding-screw, p, screwing into the arc q.

It is desirable that the clover-seeds that may be hulled by the thrashingcylinder shall not pass through the huller d f. The perforated part Mof the bottom Jis therefore made removable for substituting a clover-screen, through which the hulled seeds falling through the separator onto said bottom may fall upon shaker N beyond the opening into the huller, to pass along to the fan, While for the like escape of those hulled seeds falling directly from the thrashing-cylinder a cloverscreen, t, is placed on the shaker N,directly under the thrashingcylinder, and suiiciently above the said shaker for the seeds to escape from nnderit, and from where a passage, u, is made around each end of the huller-cylinder, the said cylinder being made shorter than the breadth of the case and shaker for this purpose. This clover-screen t is not removed when grain is thrashed. By these provisions for preventing thehulled seeds from passing through the huller there is a large percentage of saving effected, because seeds at ready hulled before entering it willbe ground or broken and destroyed.

The separator E is alike useful for and is used alike whether the machine is employed for grain or clover.

Having thus fullyT described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the separator E and shaker N, of the vibrating bottom J,con structed `with a removable perforated section, M, as and for the purpose specified.

2. The combination, with a thrashing-cylinder and concave, of the shaker N, having the ways u, the clover-screen t, mounted thereon, and the clover-hnller d f, substantially as and for the purpose set forth.

3. rThe combination, with the frame, of a clover-huller, d f, adjustably connected therewith, a shaker, N, having an aperture, and a removable section, e, for covering said aperture, as shown and described.
